Genes affected
APC (HGNC:583): (APC regulator of WNT signaling pathway) This gene encodes a tumor suppressor protein that acts as an antagonist of the Wnt signaling pathway. It is also involved in other processes including cell migration and adhesion, transcriptional activation, and apoptosis. Defects in this gene cause familial adenomatous polyposis (FAP), an autosomal dominant pre-malignant disease that usually progresses to malignancy. Mutations in the APC gene have been found to occur in most colorectal cancers, where disease-associated mutations tend to be clustered in a small region designated the mutation cluster region (MCR) and result in a truncated protein product.

Variant summary: The APC c.1419G>A (p.Gln473Gln) variant involves the alteration of a conserved nucleotide, resulting in a synonymous change. One in silico tool predicts a damaging outcome for this variant, and 3/5 splicing algorithms predict no significant change to normal splicing. Transcript analysis revealed that this variant did not disrupt normal splicing (Kaufmann_JMD_2009; PMID: 9669663). This variant was found in 21/120558 control chromosomes at a frequency of 0.0001742, which is approximately 2 times the estimated maximal expected allele frequency of a pathogenic APC variant (0.0000714), suggesting this variant is likely a benign polymorphism. In addition, several clinical diagnostic laboratories classified this variant as benign/likely benign. Taken together, this variant is classified as Benign. -
